The red/yellow/green light problem seems particularly to be an issue at night.
We witnessed this first hand on our way up the hill to Santa Fe. We stopped at the red light with 2 minutes left on the countdown and were immediately passed by a rather impatient moke. Sure enough, a few seconds later they were met head-on by a moped. It took the two parties awhile to maneuver around each other and, from the looks of the encounter, the moped offered the moke a few words of wisdom.
